Flux Pro v1.1 Ultra

Flux Pro V1.1 Ultra is an image generation model that requires each prompt to be fully self-contained. It does not carry visual context or attributes from one generation to the next, so every image request must restate all desired details explicitly (style, characters, objects, setting, composition, etc.).
